JavaScript & Node.js for backend development, who said you shouldn’t? A lot of things (good & bad) have been said about Node.js, here’s our input! Learn about advantages, disadvantages & tools for backend developers.

Node.js has evolved as one of the most popular javascript platforms to develop networking and real-time web applications. one of the many reasons why node.js is popular among the developers is that it has many tools and frameworks available for developing a scalable and lightweight application. image source: big stockin…

So for the longest time, organizing JavaScript code in multiple files required you to load each file with variables shared globally.This is actually what we’re doing with the above moment.js example — the entire moment.min.js file is loaded in the HTML, which defines a global variable moment, which is then available to…

Instead of loading all of moment.min.js with an HTML script tag, you can load it directly in the JavaScript file as follows:// index.jsvar moment = from this is how module loading works in node.js, which works great since node.js is a server side language with access to the computer’s file…

A JavaScript module bundler is a tool that gets around the problem with a build step (which has access to the file system) to create a final output that is browser compatible (which doesn’t need access to the file system).

The cluster module allows you to create a small network of some individual processes which can conveniently share server ports; this will in return gives a complete level of control and power to your server.

So, to get started with the cluster module, we need to first encounter the master process.

As the name suggests, the master process is the main controller of all the processes which can launch new programs called workers with a call to cluster.fork (), or many other related “workers” which are expected to perform common functions.

Here’s how we can do that: – – in the above process, as and when an exit event become alive, the master process will launch new child programs, to ensure an equal availability of the entire processes.

To master the Node.Js app, it is important for us to first learn the art of determining the number of child processes we wish to create and everything that matters.

note: Sequelize does support a number of other database engines; I am just most familiar with PostreSQL.Created a PostgreSQL database for this project.sudo -u postgres createdb mydbnote: My development OS is Ubuntu; so you will likely have to do some translation to your OS.Created a new PostgreSQL user for this…

Not the case, you have to provide the values yourself.With this in place, we can seed our db:seed:allForever being the pessimist, I double-checked the database to see that it did what I expected:psql * from “Todos”;With expected result of:id | note | createdAt | updatedAt 1 | Hello Todos |…

The auto-generated model file exports a factory function that creates todo models; not the model itself.Sequelize Web ApplicationIf you have been following along, we wrote the earlier web applications using in-memory persistence; at the same time we created the in-memory structures using the same patterns as Sequelize.

Previously, we had to generate a private/public key pair, send it to a trusted authority, pay them and probably wait a bit in order to get an SSL certificate.

In order to install Certbot, run – brew install certbot – – Webroot – Webroot is a Certbot plugin that, in addition to the Certbot default functionallity which automatically generates your public/private key pair and generates an SSL certificate for those, also copies the certificates to your webroot folder and…

Last but not least, after running this command, the output will contain paths to your private key and certificate files.

The primary goals for HTTP/2 are to reduce latency by enabling full request and response multiplexing, minimize protocol overhead via efficient compression of HTTP header fields, and add support for request prioritization and server push.

HTTP/2 Server Push allows the server to send assets to the browser before it has even asked for them.

In HTTP/1 the client sends a request to the server, which replies with the requested content, usually with an HTML file that contains links to many assets (.

You can see that HTTP/2 multiplexing reduced the number of requests, and the assets were sent immediately together with the initial request.

You can find the full example here: Server Push, we can send assets to the browser before it has even asked for them to reduce the initial loading time for our users.

“Callback hell is real – – Debugging is a bitch – – JavaScript was not made for server-side – – […]” – – And some are more… straightforward: – – For this post, I thought it was time to set the record straight about Node.js and JavaScript as a backend…

How can we explain the rapid shift from the original backlash to the mainstream acceptance for Node.js and JavaScript as a backend language?

Node.js not only revolutionized backend web development but also contributed to bringing performance to the frontend by bringing serious engineering to the client-side.

Let’s say you need to do video encoding, you won’t go searching for an esoteric Node.js library: you’ll simply call proven tools in the command line from Node.

I guess the aim here is to paint a grey area between the black & white opinions I’ve been reading on Node.js and JavaScript as a backend language.

In practice, this means that Prettier leverages what computers are good atâââparsing and analysing codeâââto enable smoother, easier collaboration in software development.ÂšThis is fantastic for many teams and projects, but especially for open source, where contributors are usually dispersed, often strangers, and sometimes new to the project.

Your teammates wonât be annoyed, because Prettier will prettify your code before they ever see it.There is a huge amount of formatting decisions youâll never need to think about againâââthatâs true for the individual developer and for the team.

Each individual on your team, or contributor to your open source project, can write their own stylistically idiosyncratic code and Prettier will pretty-print it before anyone else has to read it.

Or code review it.You can ensure that PRs are prettified before they are reviewed, thus removing the need for nits regarding styling or formatting.Prettier is a fantastic productivity win for developers, teams, and especially open source projects, where contributors are usually dispersed, often strangers, and sometimes new to the project….
